Lette/rs Patent No. 86,l66, dated January 26, 1869.

IMPROVEMENT IN MACHINERY FOR CLINCHING- `III-.'[CRSE-SHOE NAILS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it ma/y concern Beit known that I, DAVID KIRK, of Orleans, in the county of Ontario, in the State of NewYork, have invented a new and useful Machine for the Purpose of Glinching Horse-Shoe Nails on the hoof of the horse with less expenditure of time and labor; and I do hereby declare that the following is afnll, clear, and exact description of the construct-ion and operation of the same, reference being had to the annexed drawing, making a part of this specification.

In the accompanying drawing- A represents a bed-piece, supporting two uprightstanchions, B B, and a joint, G, having also attached a handle, K.

The stanchions B B have hung` between them, by the pivot I, a half' cog-wheel, forming part of a lever, G.

This half cog-wheel intersects with the cogs on the circular inclined. plane, forming the upper part of an eccentric, D.

This eccentric is joined with a second lever, F, at the joint P, the lever F being attached to the hedpiece by the pivot L, through the joint G.

This lever F has also a steel clincher, E, attached, the face of which is covered with rasp-like teeth.4

A spring, H, secured to the bed-piece A by a bolt,

ofl which the joint G .forms the head, supports the lever F, likewise the eccentric, D, and holds in position the cogs on the inclined plane and the half cogwheel of the lever C.

In the operation ofthe machine, the operator, supporting the foot and hoof of the horse by his knee,

grasps the handle K with his left hand, the machine toward his own person, raises the lever G with his right hand, thereby permitting' the spring H to raise the lever F to a requisite height, and places the projecting part of the bed-piece A under the shoe and bott-oni ofthe horse-hoof, the clincher E on the top of the hoof, and above the protruding nail to be clinched. The lever G is then lowered, the clinchcr E descends, pressing; the nail into the hoof', and rasping oi` the snrface, in its descent. This process is repeated till the nails in each shoe are clinched on the hoof.

What I claim as my invention, and desire to secure by Letters Patent, isv The machine constructed and arranged to operate as hereinbefore described.

DAVID KIRK.
